To measure the strength of the major muscle groups of the affected and intact lower limbs in people with stroke compared with age-matched controls.
Cross-sectional study.
University laboratory.
Ambulatory stroke survivors (n=60; mean age, 69±11y), who had had a stroke between 1 and 6 years previously, and age-matched controls (n=35; mean age, 65±9y) (N=95).
Not applicable.
The maximum isometric strength of 12 muscle groups (hip flexors and extensors, hip adductors and abductors, hip internal rotators and external rotators, knee flexors and extensors, ankle dorsiflexors and plantarflexors, ankle invertors and evertors) of both lower limbs was measured using handheld dynamometry. All strength measurements were taken in standardized positions by 1 rater.
The affected lower limb of the participants with stroke was significantly weaker than that of the control participants for all muscle groups (P<.01). Strength (adjusted for age, sex, and body weight) was 48% (range, 34%-62%) of that of the control participants. The most severely affected muscle groups were hip extensors (34% of controls), ankle dorsiflexors (35%), and hip adductors (38%), and the least severely affected muscle groups were ankle invertors (62%), ankle plantarflexors (57%), and hip flexors (55%). The intact lower limb of the participants with stroke was significantly weaker than that of the control participants for all muscle groups (P<.05) except for ankle invertors (P=.25). Strength (adjusted for age, sex, and body weight) was 66% (range, 44%-91%) of that of the control participants. The most severely affected muscle groups were hip extensors (44% of controls), ankle dorsiflexors (52%), and knee flexors (54%).
Ambulatory people with chronic stroke have a marked loss of strength in most of the major muscle groups of both lower limbs compared with age-matched controls.
测量中风患者患侧和健侧下肢主要肌肉群的力量，并与年龄匹配的对照组进行比较。
横断面研究。
大学实验室。
能行走的中风幸存者（n = 60；平均年龄69±11岁），中风发生在1至6年前，以及年龄匹配的对照组（n = 35；平均年龄65±9岁）（N = 95）。
不适用。
使用手持测力计测量双下肢12个肌肉群（髋屈肌和伸肌、髋内收肌和外展肌、髋内旋肌和外旋肌、膝屈肌和伸肌、踝背屈肌和跖屈肌、踝内翻肌和外翻肌）的最大等长肌力。所有力量测量均由1名评估者在标准化位置进行。
中风患者患侧下肢所有肌肉群的力量均显著低于对照组（P <.01）。（根据年龄、性别和体重调整后的）力量为对照组的48%（范围34% - 62%）。受影响最严重的肌肉群是髋伸肌（对照组的34%）、踝背屈肌（35%）和髋内收肌（38%），受影响最轻的肌肉群是踝内翻肌（62%）、踝跖屈肌（57%）和髋屈肌（55%）。中风患者健侧下肢除踝内翻肌外（P = 0.25），所有肌肉群的力量均显著低于对照组（P <.05）。（根据年龄、性别和体重调整后的）力量为对照组的66%（范围44% - 91%）。受影响最严重的肌肉群是髋伸肌（对照组的44%）、踝背屈肌（52%）和膝屈肌（54%）。
与年龄匹配的对照组相比，能行走的慢性中风患者双下肢大多数主要肌肉群的力量明显丧失。
